About 40 firefighters battled the flames, as well as two air tankers, a helicopter and one air attack plane, according to Cal Fire officials

Crews planned to remain in the area through the night to put out any potential hot spots.

Because of downed power lines, Tubbs Lane was set to be closed in both directions until 2 a.m.

The downed lines originally left 1,675 customers without power. As of 9 p.m., that number was down to 289, said J.D. Guidi, a PG&E representative. Those customers likely won’t have power again until 7 a.m Wednesday.

Further north, a 215-acre wildfire in east Lake County was 100 percent contained as of 7 p.m. Tuesday, Smith said. About 350 firefighters and two helicopters worked since Sunday to put out the flames. The fire broke out about 5:30 p.m. Sunday near Indian Valley Reservoir.
